If you&;ve got ringing in the ears (tinnitus), headaches or neck pain that won&;t seem to go away even with treatment? Did you know your jaw could be the cause?.Pterygoid.The Pterodactyl&;s of your body – but no actually – these wing shaped muscles are notoriously hard to feel – especially extra-orally – they are the last 2 in the muscles of mastication and their function is to assist in chewing! (Again! big surprise!) Your pterygoids are comprised of 2 parts.Medial PterygoidsLateral PterygoidsThese muscles work together to help ELEVATE and PROTRUDE the jaw. The lateral pterygoid muscle is one to note because its the ONLY muscle of mastication that can actually help open the jaw.Not all muscles are meant to just simply be released! For example – if you have a nerve entrapment of the trigeminal nerve which is a nerve in your face which also controls some muscles of sound modulation (tensor tympani, tensor veli palatini) you can have RINGING in your ears or tinnitus. This may be due to too much INACTIVITY of muscles designed to hold the jaw in its proper forward position. If the mandible shifts too far back tension can be placed on the nerve causing some of your symptoms. Confused yet? For every joint in the body, there is an optimal position, often you do not want to simply jam the joint as far back as it can go – the same applies for the TMJ.
